Executive Summary

The concept of cooperative communications in wireless networks has received considerable research attention in recent years. Cooperative methods, ranging from relaying by a common neighbour over a single wireless hop to opportunistic routing at the network layer have been shown to offer significant performance gains over traditional approaches that ignore the broadcast nature of the wireless medium, and are particularly valuable in environments prone to channel shadowing and fading, such as mobile ad-hoc networks. A common feature of various cooperative methods proposed in the literature is the initial coordination required to discover the available neighbours and determine which of those neighbours will cooperate with a given link.
